(WPTA) A Bluffton mother and her boyfriend appeared in court Tuesday on child neglect charges, and shocking details are emerging in the death of her three-year-old son, Owen Collins.

Twenty-one-year-old Breanna Arnold and 30-year-old Zachary Barnes, both of Bluffton, face preliminary charges of child neglect resulting in death. Barnes and a 16-year-old boy are charged with abuse of a corpse. Police say the teenager is a friend of Barnes.

Both Arnold and Barnes were arrested on Sunday when their trailer was deemed hazardous for harboring chemicals used to make meth.

Court documents say Barnes admitted to putting "dope in their bottles and watching them have fun," referring to Owen and his older brother.

Barnes also admitted that Owen had died Friday night and that the couple decided to wrap his body in plastic wrap and put him in a bedroom dresser drawer overnight until Barnes later put Owen inside a box, with the help of his 16-year-old friend.

Barnes admitted to taking his body twelve miles away to the woods and using the mothers nail polish remover to light the box and Owen's body on fire.

State officials have asked for an additional 72 hours to determine charges for Arnold and Barnes.

Bluffton police began searching for Owen Collins on Sunday afternoon after the toddler was reported missing. His body was found Sunday night in a nearby wooded area about 20 miles south of Fort Wayne.
